Radar systems of the future will require wideband electronically steered antennas, with sidelobes below -40 dB. Because the cost of a fully time- delay steered array is excessive, the concept of overlapped subarray (with time delay controlled at the subarray feed input) is attractive. This concept seems to have originated with Rudge and Whithers, and Tang, and recently studied for limited scan by Borgiotti. In this paper we will study the sidelobe and bandwidth properties of this system for large scan angles. The basic configuration uses a circular lens fed by a hybrid matrix (with fixed time delays at the matrix output for subarray beam collimation). When an input port on the feed is excited, a distinct subarray distribution is produced on the output face of the lens. Therefore different time delays can be applied to each subarray simply by applying different time delays to each input port. The main array has phase shifters to produce a phase tilt that scans the subarray patterns.
